Track Bolts are made with oval necks and button heads to be used for splice bars connections. The oval beck fits into the oval hole in the connector bar, thus allowing tightening of the nut without the use of a second wrench to keep the bolt from turning. These bolts are manufactured as per ASTM A-183 specifications to both a heat-treated (Grade 2) and an untreated (Grade 1) designation.

Track bolts come with heavy square nuts, and are packed in cans containing 200 lbs. of bolts and nuts. Harmer stocks a wide variety of commonly used track bolts. In addition, Harmer stocks longer length track bolts (for heel blocks and cast frogs), and can supply special size track bolts on request.

	Hex Head Bolts are usually supplied to ASTM A-325 specifications and are mainly used for crane rail joint bars with tight joints.
	Square Head Bolts are used for heel blocks and the toe end of self-guarded frogs, and can be supplied with cotter pins for use in switch rods. They are manufactured to SAE grade 5 specifications.

Railway Spring Washers are made from high grade steel and are designed to maintain bolt tension under all conditions. They are available in several varieties.
